Hallo,
also ich hab jetzt verschiedene Werte gelesen, mit denen es möglich ist, den originalen Ladelufttemperaturfühler zu ersetzen. 510, 560 etc.
Welcher Wert stimmt denn nun genau?
Ich möchte mit einem Minipoti aus der Großindustrie diesen Wert einstellen und Ruhe haben.
Also, wer weiß es genau?
MFG Mike
Richtiger Ersatzwiderstand vom Ladelufttemperaturfühler

hallo Pado 
der antwort leest du beim SJM :
This sensor has a rubber boot to keep water/dirt out. On vehicles that have the sensor hard wired into the harness, if you want to measure the resistance of this air temp sensor, you must first isolate the sensor from the ECU circuitry.
On the 1992-95 S4/S6, you can simply unplug the electrical connector at the sensor and measure the resistance directly across the air temp sensor terminals.
On the 1991 200TQ 20V, you need to remove the ECU connector from the ECU. With the ECU connector removed, the resistance measured across the air temp sensor pins or across the appropriate ECU connector pins # 44 and # 2 to check the wiring between the ECU and the resistance of the sensor.
You can also measure across terminals #44 and #30 as ECU terminals # 30 and # 2 are connected via a welded connection inside the ECU harness.
The resistance should be approximately 500 ohms at 25C (70F). The resistance measured doesn't need to be "exactly" as shown, it just needs to be close to the value shown.
